[Elecraft] Ref Oscillator Calibration procedure not working after 01.77 Firmware install

[Mike Scott]

I downloaded new firmware 01.77 and 01.58 and I wonder if something has been
introduced to make CONFIG:REF CAL procedure not work.

It worked perfectly before using zero beat method.

I set frequency to 10.000 MHZ, CW mode 2.8 KHz Bandwith, WWV is good S9
signal

I set monitor to approximately equal volume level of WWV, monitor set to 36

I use MENU button to switch to CONFIG:REF CAL, so far so good, reading is
49.379.670

I tap SPOT; VFO B display changes to SPOT, here is where the problem creeps
in. I hear the spot tone and no WWV signal whatsoever. I can adjust VFO A
until the cows come home with no change as there is no signal to beat with.
I tap SPOT again and WWV is there but no spot tone. Toggling SPOT
alternatively gives me either the spot tone or WWV signal but never both
simultaneously. The display toggles from SPOT to REF CAL. It is really clear
when the WWV signal goes away.

Now when I exit CONFIG mode and tap SPOT I immediately get the beat tone of
WWV beating with the spot tone but I can't adjust the oscillator in normal
mode. I can zero beat the oscillator by trial and error by listening to the
beats in normal receive mode with SPOT enabled and then shift to CONFIG mode
to tweak the oscillator and back out to normal mode to see if I got closer.

Either I am having a gross operator problem or something has changed.
